Method and Network Node for Pre-Scheduling Grant Transmission

摘要

There is provided a pre-scheduling grant transmission method performed by a network node. The method comprises the steps of issuing (S1) a first sequence of pre-scheduling grants on a downlink to a User Equipment, UE, providing the UE with reserved resources for uplink data packet transmission from a send buffer of the UE, collecting (S2) data relating to at least transmitted uplink traffic initiated by the transmitted first pre-scheduling grants in order to obtain a data set providing a statistical description of the traffic flow of at least transmitted uplink traffic during the time period covered by the first sequence of pre-scheduling grants, predicting (S3), based on at least a subset of the obtained data set, the time when the next data packet arrives to the send buffer of the UE; and transmitting (S4) at least one pre-scheduling grant to the UE at a time in the vicinity of the predicted time when the next data packet arrives at the UE send buffer to thereby provide the UE with timely resources to enable the UE to transmit the data packet shortly after the packet has arrived at the UE send buffer. There is also disclosed a network node configured for pre-scheduling grant transmission.
